Rb20 viscous fan blade question

Hey guys an idea what fan blades these are? Was under the impression rb20 were just straight blades and pretty archaic.

Also think there will be any issues running this fan vs the oem rb20 fan blades and the factory shroud?

Also is it alright to use blue loctite on the bolts just to ensure they don't back off?

Don't know about the fan but in general cooling system works best if you can retain (or adapt) the OEM shroud.

Hmm alright worse comes to worse I will make the oem shroud work. Gets 46*C during the summer where I live.

Use the standard shroud, it's there to direct airflow through the radiator.

That looks like an R32 fan. Straight blade came on R31s and R32 GT-Rs (unless my GT-R's fan blade was changed to an R31 one lol).

Got everything in today.  Super tight fit with ic piping. Think there is an inch clearance between fan blade and pipe.  Anyone see an issue with it being so close? Previous owner told me he tried running like this and the piping would hit the fan on hard accelerstion,he ended up putting a hole in the old rad.

Update:

Burped the cooling system and took the car for a drive, can definitely tell it's running cooler than with the old setup I had.  Drove around and revved out to 4-4.5k and didn't have any issues so we'll see when I actually do a wot pull if anything hits

How are the engine mounts? I think Nismo use harder rubbers on their mounts, if your standard ones move "too much".

I will check them out
